$(10$ marks$)$ A $5-$storey rigid frame structure with an overall height of $15\mathrm{.}0m$ and storey height of $3\mathrm{.}0m$ is shown in Fig. $1-1.$ The building is subjected to lateral forces at each storey level. The areas of beams $(A_g)$ and columns $(A_d),$ and moment of inertia of beams $(I_g)$ and columns $(I_c)$ are defined in the table below. Take $E=200$GPa. All members are rigidly connected.
